Incident Overview
A pilot initiated a flight despite a pre-existing history of brake fluid problems with the left brake cylinder. During the landing rollout, the aircraft began to veer to the right. In response, the pilot applied brakes and rudder input. However, the rudder pedals moved to the floor without effective resistance. The pilot subsequently lost directional control of the aircraft.
Sequence of Events
As the aircraft continued to deviate to the right, the left main tire blew out. The aircraft then executed a ground loop to the right, during which the left wing, wing strut, and tail section made contact with the ground. Post-incident examination of the runway revealed tire skid marks consistent with the loss of control. Inspection of the left brake cylinder showed evidence of prior leakage, and the brake cylinder was found to be empty of fluid.
Examination Findings
The investigation focused on the brake system, revealing that the left brake cylinder had leaked fluid in the past and was completely depleted at the time of the incident. No other contributing factors were identified from the available information.
